As temperatures rise, so does our dependence on air conditioners and fans. While air conditioners and fans are essential for staying cool and comfortable in summer, there are also many potential hazards to be aware of. You may be surprised to find out how many home fires are caused by air conditioning and fan equipment.

Normally, air conditioner and fan fires occur due to a mechanical or electrical failure. About one third of fires involving air conditioning or fan equipment began with ignition of wire or cable insulation.

Top 3 Causes of Air Conditioner and Fan Fires

Overuse, which causes heat buildup
Improper or lack of professional A/C maintenance
Poor electrical wiring and electrical issues

Luckily, air conditioning and fan fires can be prevented with the proper maintenance.

Follow these tips to ensure your summer cooling safety!

Central A/C Safety Tips

Always hire a qualified, licensed HVAC technician to install and service any heating, ventilation, or air conditioning equipment. Don’t try to do it yourself and possible cause further damage or injury to your home, yourself, or others.
Do not store anything near your indoor air handler unit. There should be a minimum 3-foot clearance around the unit.
Make sure all of your supply and return vents are unblocked. Check behind furniture and drapes.
Teach children to stay far away from your indoor and outdoor air conditioning units. While the units are protected by covers, it can be very dangerous and damaging if anyone tries to stick anything through the grills.
Keep the access panels and covers on at all times. This applies to your indoor air handler, outdoor condenser unit, as well as the thermostat.
Inspect and maintain AC equipment regularly, ideally before you start using it full-time.

Schedule Annual Professional A/C Maintenance

Air conditioning units need to be properly maintained by a professional. The best thing you can do to keep your air conditioner working safely and efficiently is by scheduling annual air conditioning maintenance every spring.

Professional HVAC technicians will be able to inspect your cooling system for safety issues that could result in a fire. In addition to preventing electrical problems, your certified HVAC technician will also clean your system and make sure there are no carbon monoxide or refrigerant leaks.

DIY A/C Maintenance

In addition to annual air conditioning maintenance from a qualified, licensed professional, you can help maintain your central unit by:

Changing your air filter every 30-60 days.
Making sure your outdoor unit has proper airflow by removing debris and cleaning the condenser unit

Window A/C Safety Tips

If you use a window air conditioning unit, here are some tips to make sure it is installed properly:

When selecting equipment, make sure it is rated for the size of the space you want to cool. Make sure the unit has been tested by a recognized, independent testing laboratory.
Do not plug your air conditioner into an extension cord or power strip. Your window unit should have its own dedicated outlet.
Never position window units near water or where water is likely to be spilled.
Clean or replace A/C filters according to manufacturer instructions.
Periodically inspect cords for damage, fraying, loose connections, and broken plugs. If you notice any damage, turn the unit off, unplug it, and replace the damage equipment.
Make sure the window and window frame are secure and in good condition.
Never attempt to install a window A/C unit on your own. If possible, have a professional install your window unit.
Follow manufacturer instructions carefully when installing the window unit. There should be metal brackets, mounting rails, or some sort of firm support system. If the unit does not fit properly, do not try to jerry-rig it with additional materials, such as wooden blocks.
Never put anything on top of the window unit, such as flower pots or bird feeders.
It’s a good idea to tilt the unit slightly for drainage, but make sure it’s not a steep angle.
Do not use window units in windows that serve as a fire escape.
It may seem obvious, but do not allow any pets or children to drink the water that drips from the back of the window air conditioner.
Make sure the unit is off before pulling the plug from the socket.
As with installation, never attempt to remove a window unit by yourself. Working alone is never recommended.
FYI, window A/C units cause more fires than central units. If you’re still relying on window units, speak with a professional HVAC technician about making the switch.

Fan Safety Tips

Only purchase fans that have been tested by a recognized, independent testing laboratory.
Check for product recalls at cpsc.gov.
Follow manufacturer instructions when placing or installing fans. If possible, hire a professional to install built-in or stationary fans.
Double check that air intakes are not blocked.
Always follow manufacturer instructions.
Keep fans away from water or water may be spilled.
Never plug fans into an extension cord. Plug fans directly into outlets with sufficient electrical capacity.
Periodically inspect cords for damage, fraying, broken plugs, and loose connections. Replace any damaged equipment before use.

Smoke and Carbon Monoxide Detectors

Carbon monoxide is a colorless and odorless gas that can cause serious issues, including death. Make sure you have smoke and CO detectors installed on every level of the home. Check the batteries every month and replace any units that are 10 years old or older.
